You would benefit in speed of acquisition, debt pay down and tax benefits if you use what you are already doing, just a little more purposeful.  

So instead of like 18 months ago were I presold my phase one in 3 months  ( 30 homes) then had to build them like a mad dog.. we have a better flow now we have semi custom top of the market product in the development so producing about 2 to 4 homes a month is our speed and sales so far are right in line with that absorption. 

You can calculate the amount of gallons per minute from each faucet, and then back into maybe 1/2 of all faucets being used at the same time for 15-20 minutes (peak shower time in the morning or evening).

I am searching and have found some properties that peak my interest in the Columbus area for STRs. 

You're looking at the likely peak of a lengthy upswing right now.

Purchase price: $63,000 Sale price: $207,000Our first flip and during the peak of COVID.

In a few years that likely settles down and prices drop from the peaking now for costs of good but not back down to what it was pre-corona as regular economic cycle inflation sets in for a longer term. 

My guess is I'm averaging $150 a night off-peak (November through March), $200 mid-peak (April, October), and probably $300 per night during the summer season (May through September)...with high vacancy off-peak months.

Unless your market has its price peak 6 months out I would agree you may be a bit under priced.

I am not sure of any way to speed it up.
